bold display letterforms with retro rainbow shadow stacking — 4 hard-edge offset shadow layers cascading lower-right at 5px intervals per layer. COLOR: each individual letter face contains a complete ROYGBIV rainbow gradient top-to-bottom — top=red, mid=yellow-green, bottom=violet; NOT one color per letter, every letter is its own complete rainbow. Shadow layers: layer1=red offset, layer2=orange, layer3=yellow-green, layer4=cobalt-blue — hard crisp edges, zero feathering. 50-line/inch halftone dot screen at 45-degree across letter face and shadow layers. Reference: 1970s rock poster rainbow shadow lettering / vintage silkscreen party banner. rendered with a full-spectrum rainbow gradient flowing continuously across the entire word from left to right — precise ROYGBIV color sequence: red at leftmost letter edge → orange → yellow → green → blue → indigo → violet at rightmost letter edge; the gradient sweeps across all letters as a single unified color field, not per-letter. Letter surfaces: smooth glossy material with slight convex curvature — top surface catches a narrow bright specular highlight line (near-white, 2-3px width); side faces show cooler tint of the same hue; bottom edges catch subtle reflected ground light. Prismatic edge physics: at sharp letter terminals, the concentrated spectral color creates a 1-2px crisp edge glow — red terminus at left, violet terminus at right. The gradient is highly saturated full-chroma — not pastel, not muted, not desaturated. Reference: glossy acrylic signage letter under studio lighting, Pride flag color accuracy, candy store neon sign vibrancy. Clean pure-white background. Soft diffuse overhead studio lighting — no dramatic shadows, even illumination that lets the rainbow gradient be the sole visual focus. Subtle soft drop shadow beneath letters (low opacity, wide blur, minimal offset) giving gentle lift off the white surface. No background elements, no texture, no bokeh — pure product photography white backdrop. The rainbow letters are the entire composition.
